You would need to modify the plugin to add a “Publisher URL” field — the fields are not currently filterable. If you’d like to do that:

– The fields are defined at plugins/genesis-author-pro/classes/class.Genesis_Author_Pro_Book_Meta.php

– The publisher is output at plugins/genesis-author-pro/functions/template.php in genesis_author_pro_get_book_details(), and would need to be adapted to include the link.

Note that changes to the plugin would be overwritten during plugin udpates, though.

One alternative is to use one of the three buttons to display a link to the publisher’s site instead. For example:

Thank you so much for your offer to contribute French translations. You can do so from this page: https://translate.wordpress.org/projects/wp-plugins/genesis-author-pro/stable/fr/default. (If you have a French translation file already, you can upload that with the “Import Translations” link in the bottom-left of that page.)

Hi Kari

If you plan to modify the plugin, you could change the genesis_author_pro_get_buttons function to look like this:

function genesis_author_pro_get_buttons( $post_id = '' ) {

	$buttons = array( 'button_1', 'button_2', 'button_3' );
	$values  = array();

	foreach( $buttons as $button ){

		$uri    = genesis_author_pro_get_book_meta( $button . '_uri' , $post_id );
		$text   = genesis_author_pro_get_book_meta( $button . '_text', $post_id );
		$target = ( $button === 'button_3' ) ? '' : 'target="_blank" rel="noopener noreferrer"';

		if ( empty( $uri ) || empty( $text ) ) {
			continue;
		}

		$values[] = sprintf( '<a href="%1$s" class="button button-book" %2$s>%3$s</a>', $uri, $target, $text );

	}

	return empty( $values ) ? false : implode( '', $values );

}

Note that this change will be overwritten during plugin updates, though.

You could alternatively add a script to remove the target attribute on the third button at Appearance → Customize → Theme Settings → Header/Footer Scripts → Footer Scripts:

<script>
var thirdButton = document.querySelectorAll(".single-books .book-details .button-book:nth-of-type(3)");
if (thirdButton.length > 0) {
	thirdButton[0].removeAttribute("target");
}
</script>

This won’t work if JavaScript is disabled, but it also won’t be removed after plugin updates.

I hope that helps as a starting point. If you need further help with this or other StudioPress theme and plugin customisations, I recommend the community resources here: https://my.studiopress.com/community/.
